jb stage 1 gains?

[dk79]

1) i want to know how does the car behaves with jb stage tune for m5?

2) are there any drive issues?

3) any cel?

4) abrupt throttle changes?

5) with stock 4 psi boost increase bms has posted dyno numbers with about 70whp increase while they advertise only 30-50whp, don't understand this?

6) considering stock 0 to 60 time is 3.7 and 1/4 11.8-11.9 sec what should i expect in terms of improvement with jb stage 1 at 4 psi?

i was thinking about ess flash tune but their dyno numbers show 15% increased hp over stock, jb stage 1 with 4 psi is 12% over stock so the difference is only 3% between ess and jb stage 1, ess being higher.

Just go straight to JB4 and BCM, you can then change the map to mood and situation plus any changes in mods as you do them...

Jb4 is pretty advance install so I will stick with stage 1 for now and maybe go with jb4 or flash tune. My ess flash tune in my 650xi was a champ stock 1/4 12.8 at 106mph, stage1 flash 1/4 mile 11.8 at 118 at da 3300.

I would go with BCM, too.

if your looking for the 1st step , i'd say just do the jb4 alone !

the bcm is for a more perf orientated modder , in answer to your Q's the jb4 alone will basically give you a shit ton more power across the range and you will love every sec of it ! you can alway add a bcm at anytime !

i may be mistaken here but i was under the impression it's 3.5 lbs boost and anywhere from 70-80 hp

I'm lost, for some, the JB4 with BCM is a waste of money since if you don't have a ZCP, you re pretty limited to the first map,eventually with the 2nd but some issues in their log so since I'm considering a JB4, I'm asking the same...

Only some non-CP cars can't run map 2as they don't have enough room to run map 2 and keep the AFR in check, you just need to log and check before its a guarranty thats all.

I now run meth/water injection so use map 3.
